Wladimir Klitschko retires and will not fight Anthony Joshua in rematch

Wladimir Klitschko and Anthony Joshua

Former heavyweight world champion Wladimir Klitschko has retired from boxing – ruling out a rematch with Britain’s Anthony Joshua.

The Ukrainian, 41, was knocked out in the 11th round by current champion Joshua at Wembley Stadium in April.

Joshua, 27, had hoped Klitschko would sign his rematch clause for a proposed fight in Las Vegas on 11 November.
